Age and Age Groups
Data for all indicators include persons aged ≥13 years. Note PrEP estimates include persons ≥16 years as these numbers are calculated using national pharmacy data from the IQVIA Real World Data–Longitudinal Prescriptions database (and not NHSS, which includes persons ≥13 years). These data are grouped into ten-year age groups. Age groups (rather than single year of age) are used to ensure data security and confidentiality.
